Research Complex multiphase and multicomponent flows are an ubiquitous part of almost all existing and projected energy systems, and yet our understanding of these flows remains inadequate for many engineering purposes. In particular, our ability to predict the dynamic characteristics of multiphase flows or their behavior at high concentrations is very limited. Current research is focused on several of these fundamental issues. Specific projects include studies of the dynamics and acoustics of clouds of cavitation bubbles, the formation of shock waves in these clouds, and the implications for cavitation noise and damage. Other current research on multiphase flow includes studies of granular material flow and the behavior of other concentrated suspensions. One focus is on the effects of imposed vibration on granular material flows and the potential use of such vibration in industry. Another is the role played by particle/particle and particle/wall collisions in the dynamics of fluidized beds. In both projects there is an ongoing effort to develop instrumentation to make measurements of particle motions in dense media.
